Rosemary, Rosmarinus officinalis, is an evergreen herb that may not be thought of as a landscaping plant, but is nearly always included in an herb garden.
Blooming and Leaves:
Rosemary herbs do bloom even though they are not one of the more spectacular blooming plants in the landscape. The lavender-blue flowers that it produces during the spring and summer months of the year are small and beautiful, but not really outstanding.
The leaves of this herb are quite narrow and needle-like and the stem is woody. These evergreen herbs can range in height from eighteen inches to over four feet tall.
Caring for Rosemary depends on whether the herb is an established plant or if you have just recently planted it. It will grow well in nearly any soil condition as long as it is well drained. It grows well in full or partial sunlight, but prefers the full sunlight. A slow release fertilizer can be added to the soil when the herb is planted and then again during the spring. The soil should be kept somewhat moist, but it is best if it is allowed to dry out before it is watered again. Mulch can be used to keep Rosemary roots moist during the summer months and warm in the winter months, but the mulch must stay away from the plant’s crown. Rosemary should be pruned during the spring by removing any dead wood.
Propagating Rosemary can be done by seeds or by cuttings. Seeds or seedlings can be put in the ground in the spring of the year. The seedlings should be planted somewhere between 2 and 3 feet apart. If you buy your Rosemary herbs, the 1 gallon size will quickly become established.
If you are concerned about the drainage of your soil, Rosemary can be planted in something large such as a whiskey barrel or a large clay pot. These herbs are very salt spray tolerant and will survive in one of the pot close to the beach.
Rosemary has several uses. It can, of course, be used in an herb garden where it will be used in the kitchen. But, this is not the only reason to consider this plant when looking for landscaping ideas. Larger varieties can be planted together for a hedge affect and smaller varieties can be used as ground cover. All varieties add variety to the landscape with the smell they put off when brushed up against. Rosemary has also recently began being used for topiaries.
